IMPROVEMENT IN MACHINES NEW YORK, N. Y.

FOR MAKING PAPER-COLLARS.

Specification foiniing part of Letters Patent No. 5l,36l, dated December5, 1865.

To all whom it may concern:

Be it known that I, D. M. SMYTH, ot' the city, county, and State of NewYork, have invented a new and useful Improvement in Machinery forCutting and Embossing Paper Collars; and l do hereby declare that thefollowing is a full, clear, and exact description thereof, referencebeing had to the accom panying drawings, making part of this specification, in which- Figure lis a front elevation; Fig. 2, a horizontalsection taken at the lineA a, Fig. l; Fig. 3, a face view of the upperdie, and Fig. et a vertical section taken at the line B b of Fig. l.

The same letters indicate like parts in all the gures.

The object of my invention in machinery for cutting and embossingshirtcollars out of paper is, by an intermittent motion, to feed or moveforward the sheet of paper to the required places between the cuttingand the swaging dies, and there hold it while these operations are beingperformed.

In the accompanying drawings, a represents a suitable frame, and b thebed which forms the lower pressface or die, @,and what may be termed thefemale7 portion of the shears. The lower die, c, is simplya at smoothface of metal. 1 prefer to make it of steel. There are three apertures,d d d, made in it, of the form ofthe button-holes required to be made ineach collar. These holes should be formed with sharp square edges.

A mortise,f, of the size and shape of the intended collar, is formedthrough the bed c, leaving the upper edge square and sharp, and thisforms what I term the female part of the shears. To this mortise isaccurately tted a plunger, g, which forms the male portion of theshears. This is secured to the under face of a follower, h, which istted to slide in suitable ways, t z', of the frame, so as to slideaccurately therein 5 and the lower face of this plunger g is beveled inopposite directions from the middle toward each end, so as to give thecutting-edge thereof, in entering the mortise or female part of theshears, a shear ing cut, so that by this and the accuracy with which ittits the mortise the collars will be cut with aperfectly smooth edge andwithout bending the paper, thereby avoiding a serious difficultyheretofore experienced.

The face of' the follower h by the side of the plunger is provided withan embossingdie, c3, whose surface is smooth and parallel with the faceof the die or bed c; and this is provided with three punches, d d d', soas t0 accurately tit in the apertures Z l d in the bed to punch thebutton-holes. And this embossingdie c2 should be suitably formed toemboss the imitation ot' stitching; but this makes no part of my presentinvention.

Thefollower receives an up-and-down motion from an eccentric, j, on ahorizontal shaft, k,- or the required motion may be given by other andequivalent means.

The required motion is given to the main shaft, k, by a belt-wheel, l,which receives motion, by a suitable belt, from some suitable motor.

The feeding motion for moving the paper is taken from the platen orfollower h, from which project two brackets, a a', which are connectedby connecting-rod b b', with two arms, c e', ot' a rock-shaft, d". Fromthis rock-shaft project two other arms, c e', the upper ends of whichare formed with slots fj, (see Fig. 4,) Which receive pins g g', thatproject from the ends of a bar which constitutes the front part of thefeeding-frame, composed of two side pieces, h h and two end bars, fr"fi. This feeding-frame slides on the surface ofthe bed to which thebed-die is secured, and between ways j j', and under two cross-plates,7c' and l.

The inner edges ot' the side pieces, h h', of the feeding-frame aregrooved longitudinally to receive the edges of the sheet of paper and topermitit to slide therein, and they are both of them cut away at top toreceive and permit spring griping-ngers,m m', to gripe and hold thesheet ot' paper near the two edges. These spring-iin gers are so formedthat when the feeding-frame moves in the direction of the arrow (seeFig. 2) they will gripe the sheet so as to move it toward and betweenthe dies, and slide over the sheet as the frame moves back, to enablethem to take a fresh hold of the paper for the next operation, the sheetbeing held as the frame moves back by similar gripingingers, m2 m2,attached to the cross-plates k and l.

The range of motion of the feeding-frame is equal to the width of acollar-that is, equal to the width ot' paper required for each collar-'Eand by the motions of the feeding-frame the. end of the sheet of paperis first brought under the embossing-dies, there held until it isembossed, and at the next motion the embossed part is brought to thecutters, cut off', and discharged below, and by the same motion a freshportion broughtunder the embossing-die.

As the motions of the feeding-frame are derived from the platen orfollower which carries the cutter and punches to cut out thebuttonholes, and these, in making a collar, not only pass through thepaper, but into the bed-die, it is necessary that the follower, with itscutters, should rise sufficiently to getout before the feeding-framebegins to move to feed the paper forward. Itis for that reason that thearms e e of the rock-shaft d are formed with segment-slotsff' to receivethe pins g g of the bar i of the feeding-frame, so that the said armscan move for some distance as the platen is rising, before they act onthe feeding-frame.

The other arms, c c', of the rock-shaft c are formed with slots orholes, a', (see Fig. 4,) in

which are secured the wrist-pins that frm the connection with theconnecting-rods, so that by shifting the Wrist-pins the range of motionot' the feeding-carriage can bc adjusted to any width of collar requiredto be made.

That I claim as new, and desire to secure by Letters Patent, is-

l. The reciprocating feeding-frame with the sides thereof grooved toreceive the sheet of paper, in combination with the griping-ngers,substantially as described, and having a mode of' operation such asdescribed, and for the purpose speciicd.

2. The reciprocating feeding-frame with its gripin g-tn gers operatingsubstantially as herein described, in combination With the dies forembossing and cutting the collars, substantially1 as described.
